"A striking experiment in the COM
bination of colors was performed q
short time since by Prof. Vogel at
meeting of the Physical Society Of
Berlin. He wished to demonstrate the
incorrectness of the popular notion
that yellow and blue. when mixed, al
ways make green. He took two phials.
one containing acid yellow, and the
other aniline blue. He mingled their
contents together, and the result was a
mixture not green in color, but OF .

In Il recent paper on the coinci-
dence of certain solar phenomena with
the perturbations of terrestrial magne-
tism, M. +. Marchand shows, from

cart magnetic recorder, that there ex-
lists direct relation between the ter

There is now little doubt that 1887
will be the biggest building year that
this country has ever known in rail-
roads, factories and other houses. 1t is
now estimated that 2l,000 miles of new
and 10000 miles of old railway track
will be laid this year-thus affording
the iron furnaces and steel rolling and
rail mills an abundance of work. The
cost of these railroads is estimated at
1888. 900, 900 for the new and $l00, ,000,-
600 for the old roads--or say $3.50, ,O00,-
600 of capital needed for the railroads
alone.-Public Opinion.
M. Ligner, an Austrian meteorolo-
gist, claims to have asccrtained after
careful Investigation that the moon has
an influence on magnetized needle
varying with its phases and its declina-
ton. The phenomenon is said to be
more prominently noticeable when the
moon is near the earth, and to be very
marked when she is passing from the
full to her first or second quarter. The
disturbances are found to be at their
maximum when the moon is in the plane
of the equator, and greater during the
southern than it is during the northern
declination.-Ch Chicago Times.
